I SECTIONAL DIE.

Specification of Letters Patent.

Application and April 14, 19o9.fl Serial No. 489,544.

respectively, of Dorchester and Roxbury both in the county of Suffolkand State of Massachusetts, have invented certain new and usefulImprovements in Sectional Dies,

of which the following is a specification.

This invention relates to cutting dies and particularly to that class ofdies which are utilized for the purpose of cutting blanks for use in themanufacture of bootsfan shoes.

It has for its object the provision of a die having a knife blade ofirregular form for cutting out the outline of the blank and providedwith stiffening webs formed in-.

tegral therewith interposed between the two portions of said knife bladefor the purpose of stifiening the same andretaining the outline of saiddie.

It has for a further object the provision of a meansfor securing to saidstiffening webs a second or smaller'die within the confines of the knifeblade of the larger die.

.Another object of the invention is to provide the intermediate membersWithin the confines of the knife blade with a pluralit of punchesadapted to ornament the blan: while it is being cut from a piece ofmaterial.

A further objectof the invention is the provision of a plurality ofmarking or spacing pins adapted during the cutting-of the blank to prickthe blank for the pur ose of showing the exact position of lap o theother parts of the upper stock tobe sewed thereto in the construction ofthe boot and shoe or for the purpose of centering the blank upon thelast during such construction.

It has for a further obj ect the production of a yieldable markin memberadapted to indent the blank, whi e being put from a piece of material,to form in the blank a line to serve as a guide for the stitcher durintlfie t e blankis used.

It has for a further object the adjustability of said marking memberrelative to the cutting blade of said die.

- The invention consists certain novel .features of construction andarrangement of partswhich be readily understood by reference to thedescription of the drawings and to the claims herelnafter given.

0f the drawings: Figure 1 represents an inverted plan of a die embodyingthe features of this invention. Fig. 2 represents an elevation of thesame. Flg. 3 represents a section of the same, the cutting plane beingon line 3-3 on Fig. 1. Fig. 4 represents an elevation of one of themarking or spacing pins. Fig. 5 re resents a detailed sectlon throughthe stiffening webs and the smaller die secured thereto, the cuttingplane portion of one of the smaller dies and showmg the punch mountedtherein. Fig. 7 represents a section-through the'die,the cuttin planebeing on line -7 on F1 1, an showing in elevation the adjustab e markersupporting member mounted therein. F 8 represents a sectional detailthrough the same, the cutting plane being on line 8--8 on Fig. 7. Fig. 9represents a sectional detail through the same, the cutting plane beingon line 9-9 on Fig. 7. Fig. 10 represents a plan of one of the springsinterposed between the marking member and its supporting member, andFig. 11 represents a sectional detail, the cutting plane being on linel111 on Fig. 1, and showing the mechanism for adjusting the movablemember relative to the cutting edge of the die.

Similar characters designate like arts throughout theseveral figures ofthe raw mgs.

In the drawin s, 10 represents a continu ous cutting bla e of a dieadapted to out blanks for use in the manufacture of boots and shoes, thicutting blade being provided with a pluraity of stiflening webs 11interposed between two vparts of said knife blade. The stiflenin-g webs11 are of less depth than, the knife blades 10 so that when in use thewebs never contact with the material from which the blanks are out.These stiffening webs 11 are castor otherwise formed integral with theknife blade 10 and serve to retain the shape of the die and preventitsdistortion while subjected to pressure in the process of cutting.

The stiffening webs ll ma be 'rov ded atodifierent points therein wit eroratrons 12 in each ofwhich is mounte a marking or :s acing pin 13which-are adapted, when the lank is being out, to enter the surfacePatented Apr. 19, 1910.

being on line 5-5 on Fig. 1. Fig. 6 represents an enlarged sectionaldetail through aof the material at a stated distance from the edge ofthe blank and make suitable indentations therein which will serve as auide to show the exact position of lap of t e other parts of the upperwhich are to be stitched thereto in the process of constructing the bootor shoe. The point of the marking or spacing pin 13 is sh htly withinthe plane of the knife edges of t e blade 10.

Formed integral with the cutting blade 10 and with the stiffening webs11 are other.

intermediate members 15 which project toward each other leaving aspacebetween adj acent faces thereof in which may be mounted a second smallerdie 16. This die 16 is is being died out. This die 16 is also providedwith a plurality of ornamental cut:

ting members 19 threaded, thereto as indicated in Fi 5 and 6,-thesecutting members being a apted either to cut out from the blank smallportions thereof in any desired shape or simply cut into the surface ofthe blank to leave an impression. therein and give an ornamentalappearance to that portion of the blank. In some classes of shoes it isvery desirable to ornament the blank in the manner described but in acheaper grade of shoes this ornamentation is omitted, .1n which case thepins or locking members 17 may be removed and the die 16 withdrawn fromthe die 10 and plain blanks cut therefrom in an obvious manner.

Extending from one of the stifi'ening webs 11* to ears 20 and freelyrevoluble in bearings therein are two threaded members 21 extendingthrough a member 22 provided with threads engaging the threads of saidrevoluble members 21, It is obvious that by turning the members 21 themember 22 may be adjusted toward and from one portion of the knife blade10.

In vertical openings through the member I nterposed between the member22 and the members 24 are a plurality of flat springs 26 provided withnotches 27 at their ends,

into which the upper edge of the blade 24 extends. Each spring 26 alsohas a central opening 28 which surrounds the reduced end 29 'of anadjusting screw 30 mounted in the member 22 and adjustable to regulatethe tension of the springs 26. Interposed between this adjusting screw30 and the blade 24 is also a spiral s ring 31, the tension of which islikewise a justed by turning said screw 30. When the tension of thesprings has been properly adjusted the screw 30 is prevented fromturning by means of the check member 32 threaded to said member 22.

This provides a very convenient form of die cast or otherwise formed inone piece with a continuous cutting knife blade stiffened by means ofsuitable webs formed integral therewith, these webs providing means forsecuring thereto in any convenient location marking or other spacingmembers adapted to serve as guides for the lap of other portions of theupper to bestitched thereto or to receive cutting members which areadapted to cut into the face of the material or through the material aplurality of ornamental designs or imitation stitches. It provides ameans of utilizing the same die for cutting plain blanks or forsimultaneously cutting the blanks and cutting or impressin thereinornamental designs while it provides a means of detaching the secondornamentin die and substituting therefor other secon ary dies of anydesired form to vary the design to be impressed into'the blank. It alsoprovides a ready means of marking into the surface of theblank, at thesame time that the blank is being cut, a line of indentation which mayserve either for ornamenting the blanks or as a guide for the stitcherin the construction of the boot or shoe for which the blank is used andit provides a means for adjusting the position of this marking memberrelative to a portion of the cutting blade and also a means forpermitting the marking member to yield under pressure.

It is believed that from the foregoing description the operation andmany a vantages of the invention will be thoroughly understood.

Having thus described our invention, we claim: r v

1. A die of irregular forni having a con-- tinuous cutting blade, andstiffening webs formed integral with said continuous blade andinterposed between the inner faces thereofbut separated from each other;an ornamental cutting member ada ted to be positioned between said webs;and means for securing said cutting member to said'webs.
